Protector structure for electrical component

Abstract

A protector structure for an inverter 1 which is an example of an electrical component includes a protector 3 including a protection portion 31 , an attachment portion 32 A and an attachment portion 32 B. The protector 3 has a constricted portion 33 A between the protection portion 31 and the attachment portion 32 A, and has a constricted portion 33 B between the protection portion 31 and the attachment portion 32 B.

The invention claimed is: 
     
       1. A protector structure for an electrical component that comprises a case, the protector structure comprising:
 a protector including:
 a protection portion configured to protect the electrical component from a collision of a colliding object, and 
 a plurality of attachment portions attaching the protecting portion to the electrical component; wherein:
 each of the plurality of attachment portions comprises a contact portion coupled to the electrical component by a bolt, and in surface contact with the electrical component, 
 the protection portion has a flat plate shape; 
 
 one or more constricted portions between the protection portion and a respective attachment portion; wherein the one or more constricted portions have:
 a constriction with respect to the protection portion and the respective attachment portion, and 
 a lower strength than the protection portion and the respective attachment portion. 
 
 
 
     
     
       2. The protector structure for the electrical component according to  claim 1 , wherein:
 a gravity center of the protector is disposed in a region surrounded by an outer edge of a region formed by connecting connection base portions of the protection portion with the plurality of the attachment portions. 
 
     
     
       3. The protector structure for the electrical component according to  claim 1 , wherein:
 a region surrounded by an outer edge of a region formed by connecting connection base portions of the protection portion with the plurality of the attachment portions and a collision portion of the colliding object overlap each other when viewed along a vehicle front-rear direction. 
 
     
     
       4. The protector structure for the electrical component according to  claim 1 , wherein:
 the case includes a receiving portion that is raised higher than a surrounding position at a portion where the protection portion faces. 
 
     
     
       5. The protector structure for the electrical component according to  claim 4 , wherein:
 the receiving portion is formed of a rib having a mesh shape, and 
 a size of a cell of the mesh shape is smaller than a size of a collision cross section of a collision portion of the colliding object. 
 
     
     
       6. The protector structure for the electrical component of  claim 1 , wherein:
 at least one of the plurality of attachment portions is coupled directly to the protection portion without the one or more of the constriction portions therebetween. 
 
     
     
       7. The protector structure for the electrical component of  claim 1 , wherein:
 each of the plurality of attachment portions is coupled to at least one of the one or more constriction portions.
